14 Claims.

My invention relates to improvements in receptacles for use particularly as a container for coffee and for measuring and dispensing selective quantities of such material.

The important object of the invention is to provide an efficient device for hermetically sealing a coffee container, adapted for use to measure 9. selected amount of the material while the container is hermetically sealed and to provide for dispensing the measured amount while at the same time maintaining the sealed condition of the container aforesaid.

The invention will be fully and comprehensively understood from a consideration of the following detailed description when read in connection with the acompanying drawing which forms part of the application, with the understanding, however, that the improvement is capable of extended application and is not confined to the exact showing of the drawing nor to the precise construction described and, therefore, such changes and modifications may be made therein as do not affect the spirit of the invention nor exceed the scope thereof as expressed in the appended claims.

In the drawing:

Fig. 1 is a vertical, sectional view of the con.- tainer equipped according to my invention;

Fig. 2 is a top plan view; and

Fig. 3 is a horizontal section taken on line 3-3 of Fig. 1.

Referring to the drawing by numeral, I designates a container which may be of any suitable shape and which is preferably cylindrical and is provided with a cover or closure such as shown at 2 in the drawing. Mounted upon the cover 2, axially thereof, is a member 3 forming an open top measuring cylinder having a bottom end portion 4 provided with an inlet aperture 5. Within the cylinder 3, extending axially thereof, is a squared shaft 6 having its lower end rotatably mounted in the bottom portion 4 of said cylinder 3. Fast on the lower end of the shaft 6 is a shuttle member 'I for the aperture 5 and adjustable to aperture closing and. opening positions, respectively, the shutter being located exteriorly of the cylinder 3, as will be clear from Fig. 1. n the shaft 6, above the end portion 4, is a washer 8 bearing against a boss 9 on said shaft and urged upwardly by a spring III. A flange II located on the shaft 6, exteriorly of the shutter I, limits the upward movement of the shaft Ii under the urge of the spring Ill, whereby said shutter is yieldingly clamped against said portion 4 of the cylinder 3.

The shaft 6 and. shutter member I together with the aperture form a valve in the member 3 communicating with the chamber therein formed by the end 4 and the bottom of the piston I2.

Telescoping in the cylinder 3 is a cylindrical stopper I2 forming a rotatable reciprocable piston having a lower end wall I3 and an upper end wall I4 and formed with an axial sleeve I5 open at its opposite ends and receiving the 10 squared shaft 6. At its lower end said sleeve is slidably connected to the shaft 6 by means of a washer I5 secured in any suitable manner in an enlargement I6 of the sleeve I5 so that said I sleeve and shaft are keyed together. At the upper end of the sleeve I5 is a relief valve in the form of a ball Il seating in the upper end of said sleeve under the urge of a coiled spring I8 seating against a shoulder I9 formed below a relief opening provided in the end portion 2 I4 of the stopper I2.

Within the container I is an inclined chute 2I upstanding from the bottom of said container and leading to the inlet aperture 5 of the cylinder 3.

As will be clear, the stopper I2 is slidable in the cylinder 3 to different positions to vary the capacity of the latter and is rotatable in said cylinder to adjust the shutter l to opening or closing positions by virtue of the before described connections between the sleeve I5 and the shaft 6. The parts are so arranged that the stopper I2 may be completely withdrawn from the cylinder 3 so that the contents of the latter may be discharged. For this purpose a limiting collar 22 is fast on the upper end of the shaft 6 to be engaged by the washer I5 when the stopper I2 has been sufficiently withdrawn and to prevent its complete removal from the shaft 6.

Suitable means, such as the numbered graduations 23 are provided on the exterior face of the stopper I2 to register with a stationary part of the device so that the stopper may he slid to set positions to measure the amount of substance in the measuring cylinder 3.

The position in which the stopper I2 is to be rotated to adjust the shutter I to opening and closing positions is indicated by an arrow 24 on said stopper and ribs 25 on a stationary part of the device suitably designated by the words "open and closed and designated 26 and 21, respectively.

Referring now to the operation, the stopper I2 is first set according to the amount of the substance it is desired to abstract from the container I, by sliding said stopper in the cylinder 3 until the graduation 23 corresponding to the dwired amount is in register with the top of the cover 2. Said stopper I2 is then rotated by means of the hand grip 28 to adjust the shutter I to its opening position. The container I is then tilted so that the substance is caught in the chute 2| and directed therefrom into the aperture 5, after which the stopper I2 is rotated to move the shutter I to its closing position. We now have a measured quantity of substance in the cylinder 3 and the contents of the container I is hermetically sealed. The stopper I2 is now withdrawn from the cylinder 3 to the limits of its movement, as determined by the collar 22 and washer I5 and the contents of the cylinder 3 may be discharged. When the stopper I2 is again inserted in the cylinder 3 any back pressure of air or gas due to such insertion will find an outlet through the sleeve I5 and ball valve I1 and opening 20, as will be clear.

What I claim as new is:

1. In a device of the class described, a container, a cover therefor including an open top measuring cylinder having an inlet aperture in its lower end, a cylindrical stopper closed at its lower end, slidable to diiferent set positions in said measuring cylinder to vary the capacity of the latter and also rotatable in said cylinder, a shutter for said aperture and adjustable to opening and closing positions, respectively, and operating connections between the stopper and shutter for adjusting said shutter to opening and closing positions by rotation of said stopper in any set position of the latter.
